GM 8.25" Cast Iron Corvette - Ring & Pinion


Package Includes:

(1) Ring and Pinion Gear Set (Choose Ratio Above)

- *Note: This ring & pinion set has a 30 spline pinion. 1963 & 1964 Corvettes came stock with a 17 spline pinion, those applications will require a 30 spline yoke. Please verify your pinion spline count prior to ordering.

- Rigid Axle's aftermarket ring and pinion gear sets are made from heat treated 8620 steel. Our aftermarket gear set is made using a five-cut, face milled manufacturing process. Once set up correctly, this will give a square contact pattern on the drive and coast side of each tooth. We are proud of our ring and pinion lines, and you will be too!
